Specification of Letters Patent.

Patented July 23, 1907.

Application filed March 7,1907. Serial No. 361,041.

To all whom it may concern:

Be it known that I, BELONIE JAN LLE, a citizen of the United. States,residing at Manchester, .in the county of Hillsboro and State of 'NewHampshire, have invented new and useful Improvements inFilling-Replenishing Mechanism for Looms, of which the following is aspecification.

My invention pertains to filling replenishing mechanism for looms of thetype embodying filling feeders that are rotatable step by step; and ithas for its object to improve such mechanism by the provision of simpleand durable means calculated to so move the feeder after afilling-carrier is transferred therefrom that the next filling-carrierwill rest in a position exactly over the position in which the shuttleis placed to receive filling, this with a view of assuring the propersupply of filling to the shuttle at intervals during the operation ofthe loom.

With the foregoing in mind, the invention will be fully understoodfromthe following description and claims when the same are read inconnection with the accompanying drawings, forming part of thisspecification, in which:

Figure 1 is a view of so much of a well known type offilling-replenishing mechanism as is necessary to illustratethearrangement of the preferred embodiment of my invention. Fig. 2 is anenlarged side elevation of the lever comprised in my improvements, andthe appurtenances thereof. Fig. 3 is an enlarged detail plan of theupper end thereof. Fig. 4 is an enlarged, detail section taken at aright angle to Fig. 2, and in the plane indicated by the line 4-4 ofFig. 2.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is a stand on which is mounted a rotary filling feeder B which ispreferably of the ordinary, well known construction, though it may be ofany other construction compatible with the purpose of my inventionwithout involving departure from the scope of the appended claims. Thesaid stand A is provided with the usual lateral projection a, and to itis connected a filling-carrier transferrer G which is provided with alateral arm b for cooperation with my improvements, and is otherwise, bypreference, of the ordinary, well known construction and connected tothe stand A in the usual manner.

Fixed on a sleeve connected to one of the disks of the rotary feeder Band arranged outside the stand A is a ratchet wheel D having teeth 0corresponding in number to the holding devices for filling-carriers inthe feeder, while fulcrumed on the lateral projection a j of the stand Ais the vertically-swinging lever E of my improvements. Also fulcrumed onthe said projection a is a gravitating dog F which has for its ofiice toprevent retrograde movement of the ratchet wheel D and feeder B.

The lever E is provided inits lower arm with a curvilinear slot darranged to receive the lateral arm b of the transferrer C, and at theupper end of its upper arm it is provided with a transversely slottedhead 0 in one end of which bears a screw f, locked against casualmovement by a jam nut g, for a purpose set forth. In the slot of thehead 6 is adj ustably arranged a bolt h having a collar 11 at anintermediate point of its length, positioned at the inner side of thehead, Figs. 3 and 4, and also having its outer end threaded to receive anut j between which and the outer side of the head is interposed ametallic washer is. The bolt h is adjustably fixed in the slot of head ethrough the medium of the nut j, and casual backward shifting of saidbolt while the mechanism is in use is effectually prevented by the screwf against the inner end of which the bolt rests, as

illustrated.

On the inner portion of the bolt 71, is loosely mounted avertically-rocking pawl M, the forward end of which is arranged toengage the teeth 0 of ratchet wheel D, and surrounding said bolt h, atthe inner side of the said pawl M, is a coiled spring N which terminatesat one end in a-forwardly extending arm m having a loop at at its endarranged over the pawl M, and at its opposite end in a rearwardlyextending arm 10 having a loop 1 at its rear end arranged over theforward arm of lever E. Thus it will be apparent that the said pawl mwill be yieldingly held against the teeth 0 of wheel D and will alwaysbe in position to properly engage the said teeth.

In the practical operation of my improvements, it will be seen that whenthe forward portion of the transferrer G is moved downward to transfer afilling carrier from feeder B to the shuttle, the arm b on saidtransferrer will be moved upward, when said arm b coacting with theslotted arm of lever E will depress said slotted arm of the lever andraise the forward arm thereof with the result that the pawl Mwill bemoved back on ratchet wheel D the distance of one tooth. Then when theforward arm of transferrer O is raised and the arm b is depressed, thepawl M will turn the wheel D and through said wheel D the feeder B inthe direction indicated by arrow the distance of one tooth, and by sodoing will correctly position the'filling-carrier following the one thatwas displaced so that said filling-carrier will rest in exactly theproper position to be trans-- ferred to the shuttle on the succeedingoperation of the transferrer C.

It will be gathered from the foregoing that my improvements are simplein construction and reliable in operation, and that all of the partsthereof are well adapted to withstand the usage to whichfilling-replenishing mechanism is ordinarily subjected.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

1. In a filling replenishing mechanism for looms, the combination-of astand, a rotatable filling feeder mounted on the stand, a ratchet wheelfixed with respect to the filling feeder and arranged at the outer sideof the stand,

a Vertically swinging transferrer connected with the stand and having arear, lateral arm, a vertically swinging lever fulcrumed at anintermediate point of its length on the outer side of the stand andhaving a rear, slotted portion receiving the rear lateral arm of thetransferrer, and

means on said l'everffor engaging the ratchet wheel and rotating thefilling feeder step by step on the upward movement of the transferrer.

2. In a filling replenishing mechanism for looms, the combination of astand, a rotatable filling feeder mounted on'the stand, a ratchet wheelfixed with respect to the filling feeder, a vertically swingingtransferrer connected with the stand and having a rear, lateral arm, avertically swinging lever fulcrumed at an intermediate point of its lenisis length on the stand and having a rear, slotted arm receiving therear lateral arm of the transferrer and also hav ing a slotted head onits forward arm, a bolt adjustably fixed in the slot of said head, ascrew bearing in the head and arranged to prevent backward movement ofsaid bolt, a pawl loosely mounted on the bolt and arranged to engage theteeth of the ratchet wheel, and a coiled spring surrounding the bolt andhaving one arm engaging the lever and another arm engaging the pawl.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
